It is the ideal lens for street photography, to travel light or in studio

The Zeiss 35mm F1.4 is a little bit better in term of sharpness , but much more heavy , very big and twice more expensive. It has a better AF and is better in low key , low light situation thanks to his bigger aperture. His usage over the 35mm F2.8 is only worth if you do creative work (e.g. full body portrait, low depth of field landscape, wedding) or if you shoot frequently at night

le Zeiss Batis is the more “beautiful” with his Otus like lines , it also has a depth field electronic screen on the lens. handy but quite useless in practice (you will rarely look after making the AF on the lens what is the depth of field in cm)

Mon choix personnel

le Zeiss Batis 85mm , principalement pour le studio et le indoor

si mon usage était plus en extérieur je pencherais pour le 85GM

et en cas de budget plus limité le FE85mm est un maitre achat

My personal choice

le Zeiss Batis 85mm , mainly for studio and indoor

if I would be shooting outdoor mainly : the 85GM

in case of limited budget the Sony 85 F1.8 is a very good bargain and you will not regret it

I politely disagree regarding your 55 to 50 f1.4 comparison. The 50 mm has a color rendering and particular character that is lacking on the 55mm.
As good as the 55 is, I had it for 2 years; the 50mm f1.4 provides uniqueness. Cheers. Didier.
